Eitzen, Rockville Centre, N. Y., 'assignor to News Projection Corporation, New York, N. Y., a. corporation of New York Application September 4, 1929, Serial No. 390,372 Renewed May 27, 1933 13 Claims.

My present invention relates generally to stock ticker apparatus and has particular reference to a stock ticker projection machine.

A particular object of my present invention lies in providing eficient and simple mechanism for drying the tape, i. e., drying the ink orpigment thereon, in a quick and reliable manner.

In communities where the rental or purchase value of tickers is relatively high, it is frequently If) desirable to allow the marked tape toaccumulate in a basket or the like and not to be completely rewound, so that perusal of the tape afterit has passed through a suitable projecting device and at a considerably later time may still be possible without inconvenience. Frequently, in moist climates, such subsequent examination of the tape is accompanied by considerable .annoyance because of the fact that the ink or pigment has not completely dried. Similarly, regardless of climate, the employment of a tape which is not of paper but of a more transparent character such as cellophane, is similarly accompanied by a very slow drying of the markings on the tape.

One of the main features of my present invention lies in providing means for blowing air over the tape in a simple and expeditious manner for emciently and rapidly drying the tape to render it subsequently examinable without undue inconvenience. V v In a preferred embodiment, I provide, incombination with a stock ticker and a projecting device, a housing mounted beneath the ticker and projector and containing a tape-pulling mechanism; and I provide means mounted within this housing for blowing air or a similar drying medium over the tape after the latter has passed through the projecting device.

A further object lies in providing a mechanism which allows for selective adjustment for either re-winding the tape immediately after its passage through the projecting device, or for directing the tape in a loose condition into a suitable receptacle. Where the tape is immediately rewound, the previous drying thereof assures an unsmudged condition of the rewound tape so that the same may be re-projected or re-examined without annoyance.

Another object of my invention is to provide a construction wherein the means for drying the tape fulfills an additional function in connection with the cooling of the projecting device. A double advantage is achieved by me in drawing the heated air out of the projecting device and simultaneously employing this heated air for the purpose of drying the tape.

An important feature of my invention lies in providing a mechanism wherein a. single driving apparatus serves simultaneously to operate not only the tape-pulling mechanism but also the blower or similar instrumentality for providing 5 the requisite air.

In general, it is an object of my invention to provide an apparatus which is simple in construction, inexpensive to manufacture and install, and efiicient and reliable in operation. 10

For the attainment of the foregoing objects and such other objects as may hereinafter appear or be pointed out, I have illustrated one form of. my invention in the accompanying drawings, in which- 15 Figure l is an elevational view partly in section of an assembly embodying the features of my present invention; and

Figure 2 is a side view, also partly in section.

I have shown a stock ticker l0 adapted to discharge a marked tape II, the latter passing through a projecting device 12 of substantially customary construction. For example, the projecting device l2 comprises the main housing l3 within which illuminating means are provided, and the lateral housing i4 through which the tape passes, the housing I4 carrying above it a suitable objective lens or the like l5 for projecting the beam of light upwardly onto a screen.

In accordance with my present invention, I 30 mount the ticker l0 and the device I 2 above a housing or chamber l6 within which the tapepulling mechanism and other elements of my present construction are arranged. I have, for example, provided a tape-pulling mechanism 35 which consists of a spindle I! constantly rotated by means of a worm wheel l8 axially mounted therewith, the wheel l8 deriving its motion from a worm 19 mounted upon a shaft 20, the latter being driven by means of a belt 2| or the like 40 from the shaft of an electric motor 22. The tape II is caused to pass beneath a guide roller 23, thence over and around the spindle ll, thence underneath the guide roller 24, from which latter point it may be directed either onto 5 a receiving and re-winding mandrel 25 or through a suitable outlet opening in the housing 16, as shown in full lines in Figure 1. Thedot and dash line 26 of Figure 1 illustrates the manner in which the tape may, if desired, be directed immediately onto the receiving mandrel 25.

The mandrel 25 is driven from the shaft of the spindle I! by means of a belt or the like 21, and a guide roller 28 adjacent to the outlet opening previously mentioned is caused to rotate by 55 means of a belt or the like 29 extending from the shaft of the mandrel 25. A. spring-pressed roller 30 bears against the tape as the latter passes over the spindle H.

In accordance with my present invention, I provide a conduit 3| constituting a narrow elongated housing for completely enclosing the tape II during its passage from the projecting device l2 to the tape-pulling mechanism and thereby positively protecting it from engagement by a trader. The upper end of this conduit is restricted and below such restriction is in communication by means of an opening 32 with the interior of the lateral projecting device housing M, and the latter is in communication with the interior of the main housing 13 by means of the suitably prepared apertures or openings 33. The conduit 3i extends downwardly into the chamber i6 and terminates closely adjacent to the first guide roller 23, at which point it is again restricted by a hinged or pivoted cover 34 which permits access for the purpose of threading or inspection.

Mounted upon the shaft of the motor 22 is a blower 35 whose inlet opening 36 is caused to communicate with the interior of the conduit 3 I. I have illustratively shown a pipe 31 opening into a chamber 38 adjacent to the conduit 3| and provided with apertures 39 communicating with the interior of the conduit 3|. It is to be noted that these apertures are so arranged as to apply the suction of the blower edgewise with respect to the tape.

When the apparatus functions, the motor serves not only to drive the tape-pulling mechanism, the re-winding mechanism and all the other portions belted or connected thereto, but also to operate the blower 35. This causes heated air to be drawn out of the housing 13 through the openings 33 and then through the opening 32 into the upper end of the conduit 3|, thence downwardly. At this stage, the heated air serves to dry the tape passing through the conduit. At the lower end of the conduit, the air passes outwardly through the apertures 39 into the chamber 38 and thence through the conduit 31. In this way, the projecting device is not only kept in a cooled condition by the removal of the heated air, but the tape is at the same time efiiciently dried by means of this same heated air.

It will be obvious that the employment of this apparatus is an extremely inexpensive matter. At the same time, it is to be noted that an efiicient drying of the tape is accomplished, whereby the latter may be subsequently examined and handled without inconvenience. For example, the tape H emanating from the left side of the apparatus in Figure 1 may be caused to collect in a basket or suitable receptacle, and whether this tape be of paper or any other material, and whether the climate be moist or dry, free inspection may be had of the collected tape without any danger of smudging the latter or soiling the hands.

It will be obvious that changes in the details herein described and illustrated for the purpose of explaining the nature of my invention may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is therefore intended that these details be interpreted as illustrative, and not in a limiting sense.
